Reverse direction F-1blower mounts further forward with the intake facing front.

You can see the blower requires about 6 inches but also need an air cleaner

We need to add the surge valve and the blow off valve

The blow off would limit boost and also release any backfire pressure.

A conventional rotation blower would be turned around, see how nice it would fit.

The intake would face the rear.

With only 5psi boost and 3000rpm we could use the one serpentine belt

or for reliability we could use a seperate belt. Should the blower belt fail, the engine would still run with accessories.

Surgle valve is kept open with vacuum at less than full throttle making no boost
